Be it known that 1, JOHN Pi-nrrr JKIPP, a citizen of the United States,residing at Detroit, in the county of Wayne and State of Michigan, haveinvented certain new and useful Improvements in Pipe-Joint F asteners,of which the following is a specification.

This invention has for its object to provide a connection or fastenerfor the adjacent ends of sections of stove pipes to effectively preventwithdrawal of one pipe section from the other and further to reliablymaintain the sections in proper alinement, thereby preventing sagging atthe joints and eliminating the necessity of use for supporting wires.

A further object is the provision of a device of this characterembodying features of simplicity affording its economical manufactureand possessing novel structural details permitting of its quick andconvenient application to use and also of its utilization 1n perforatingthe pipe for the accommodation of the fastener.

With these and other objects in view, the invention consists in certainnovel features of construction as hereinafter shown and described andthen specifically pointed out in the claims, and in the drawingsillustrative of the preferred embodiment of the invention.

Figure 1 represents a perspective view 7 of the improved pipe fastener.

Fig. 2 represents a plan view thereof, and,

Fig. 3 represents a side elevation of the fastener applied to theadjacent ends of pipe sections. 7

Referring to the drawing in detail, wherein similar-reference numeralsdesignate corresponding parts throughout the several views the numerals5 and 6 indicate generally the companion parts of the fastener which arepreferably constructed of Wire possessing a requisite degree ofresiliency to permit the necessary fiexure thereof, the

member 5 consists of an elongated shank having one terminal offset asindicated at 7 and extended in parallel relation to the shank as at 8and provided at its extremity with a penetrating point 9. The oppositeterminal of the shank 5 is flattened as indi cated at 10 to increase theresiliency thereof inone direction and is pivotally connected by a rivetor other fastening element 11 with the flattened medial portion 12 ofthe shank of the other member 6.

7 Application filed August 10, 1920. Serial No. 402,577.

*One terminal of the member 6 is offset as at 18 similarly to the offsetterminal of the shank 5 and is provided with a penetrating pointl4c,whereas the opposite terminal of the shank 6 is provided with alaterally projecting' hook 15 so arranged as to partially embrace theshank 5, when the parts of the fastener are moved to operative position,to maintain the parts of the fastener in alinement and to preventaccidental separation of the shanks. I

In applying the invention to use, the shanks 5 and 6 are swung intoproper angular relation and are used in the manner of a compass inmarking the adjacent portions of two telescopically engaged pipesections 16. Y The sections of the pipe are subsequently perforated atthe points marked thereon with a suitable perforating instruby swingingone of the shanks at right angles to the other and grasping one of themin the hand, thus disposing the othershank for convenient use inoperating upon the pipe. Subsequent to the perforation of the pipesections the pointed extremity 9 of. the shank 5 is inserted in'the pipeand is disposed in such position that the shank is disposed insubstantially parallel relation thereto. The other shank 6 issubsequently swung into angular relation to the shank 5 until thepointed terminal thereof is so disposed as to enter the other hole intheadjacent pipe section, whereupon the last mentioned terminal isinserted in the pipe and the shanks 5 and 6 are swung together. Byspreading the portions of the shanks apart the hooked terminal 15'ispermitted to pass the shank 5 and being engaged behind and partiallyembracing the shank 5 effectively maintains the parts of the fastener inalinement and also the sections of the pipe.

The preferred embodiment of the invention is disclosed in the drawingsand set forth in the specification, but it will be understood that anymodifications within 75 ment or, if preferred, either pointed termithescope of the claims may be made in the construction without departingfrom the principle of the invention or sacrificing any of itsadvantages.

What is claimed is:

1. A fastener for stove pipes including a pair 01 ivotally connectedshanks provided with ofiset ends terminating in penetrating pointslocated outwardly of the ofiset shank portions of a hook carried by oneshank adapted to engage the other shank to maintain the shanks inalinement, said shanks being resilient and capable of separation topermit the hook to pass said other shank.

2. A stove pipe fastener including a pair of shan s each having anoffset penetrating point, means pivotally connecting the inner terminalof one shank with the other shank at a point onthe latter inwardly ofthe ofi set terminal, and a laterally projecting hook carried by thelast mentioned shank adapted to partially embrace the first mentionedshank to prevent accidental separation of the shanks, said shanks beingformed with resilient material permitting separation thereof forfacilitating disengagement of the hooked terminal oi one shank fromengagement with the other shank.

In testimony whereof, I affix my signature hereto.

JOHN PHILIP KIPP.
